摘　　要：钢-混凝土不规则组合框架体系对于线下式高铁站房具有良好的适用性。依托济南至莱芜高速铁路历城站结构设计,研究了钢-混凝土不规则组合线下站房结构设计的关键技术。研究结果表明:采用民用建筑规范与铁路规范相协调的设计方法,能较好地满足线下式站房的要求;钢-混凝土不规则组合结构中的侧向组合能够有效减少上下组合结构中的鞭梢效应;超长门厅钢拱组合桁架采取“抗放结合”的处理措施,可有效解决温度应力的影响;钢混锥台过渡转换节点能确保混凝土与钢结构转换的可行性与可靠性。通过对结构进行动力弹塑性分析,验证了该组合结构满足了既定的性能目标,安全可靠。The irregular steel-concrete composite frame system has good applicability for the offline high-speed railway station building.Based on the structural design of Licheng Station of Jinan-Laiwu high-speed railway,this paper studies the key technology of structural design of station building under line and irregular steel-concrete composite.The research results show that:the design method of coordination between civil building code and railway code can better meet the requirements of offline station building;the lateral combination in the irregular steel-concrete composite structure can effectively reduce the whipping effect in the upper and lower composite structure;the influence of temperature stress can be effectively solved by adopting the treatment measure of“anti-release combination”for the steel arch composite truss of the super-long foyer;the transition joint of steel-concrete cone platform can ensure the feasibility and reliability of the conversion between concrete and steel structure.Through the dynamic elastic-plastic analysis of the structure,it is verified that the composite structure meets the established performance objectives and is safe and reliable.
